IMPROVEMENT IN SHINGLE-MACHINB.

The Schedule referred to in these Letters Patent and making part ol the same To all whom it muy concern Beit known that I,`GUsTAvUs WAI/TON, of Minneapolis, in the county of Hennepin, and State of Minnesota, have invented a new and useful Improvement nmachinery for operating the ,Feed Apparatus in Sliingde-Machines; and I declare the following to he a full and exact description thereof, reference being had to the :ic-conipanyiner drawings andletters of reference marked thereon, making',r part of this specification.

To enable others to make and use my invention, I will describe its construction and operation.

The accompanying drawing represents thatA portion of a shingle-machine which carries the power from the inain or saw arbor to the feed appnmtus,

a aa a is the wooden frame-work in which this por,- tion of the machine is set.

A is an iron ur-.\or driven by belting from the saw arbor l'nnninpr on l5.

G is a friction pulley-clutch ot'iron fitted onto A, with corresponding sectional pieces b b; over C are fitted washers ot' sole-leather sufficient to make a friction surface three or four inches in width.

Thes'ewushers are iirmly secured bythe. iron washer D andthe nut E. y

F is an iron friction-Wheel on the arbor G of fifteen inches diameter and having smooth rim of width corresponding.r to the friction surface of washers on C.

lVhen A is driven and C is brought against F by means of lever and ratchet at H, the motion is cominunicated at G, and the feed apparatus propelled by a small beveled gear at 1.

The advantages of frction over gearing in this part of the machine are, the securing a niore steady and even motion, and the avoiding the expense and delay incident to tbe breaking out of cogs, frequently bnppenin'g wheuthe feed-pinion strikes back into gear as the carriage motion is reversed.

I am aware that the various devices employed in my machine -zire not new, therefore I do not claimthem separately; but What I do claim isf The arrangement of feeding devices, consisting of the cone pulley B, shaft A, clutch b, leather-covered ti'iction-wheel C, lever-paw] and ratchet H, iron friction-wl'ieel F, shaft G, and frame a a, the whole heilig constructed as herein described for the purpose specitied.
